BRUSH FOR COTTON-CLEANERS.

To all whom it may concern:

Beit known that I, EDWARD A. RozIER, a citizen of the United States, and a resident of Sparta, in the county of Hancock and State of Georgia, have invented an Tmprovement in Brushes for Cotton-Cleaners, of which the following is a specification.

My present invention relates to cotton cleaners and more particularly to the brushes utilized in connection with gin mechanisms to clean the saws, my object being to provide a device embodying oppositely projecting series of brush elements adapted for rotation between gin saws in such manner that the brushes operate against the sides of the gin teeth.

The object of my invention is to provide an arrangement in which the series of brushes are adjustable away from one another in order that the pro-per engagement between the brushes and the saws may be maintained at all times and the wear of the brushes compensated for it.

In the accompanying drawing which illustrates my invention, Figure 1, is a sectional side elevation through the waste chute and the brush shaft, illustrating my improved brush in side elevation. ,Fig. 2, is a side elevation of the brush wheel with the brush heads removed. Fig. 8, is a vertical transverse section through the brush wheel, taken substantially on line 33 of Fig. 1. Fig. 4, is a detail horizontal section through the brush wheel and a pair of the brush heads taken substantially on line ll of Fig. 1, and Fig. 5, is a vertical section through the central portions of two brush disks showing a spacing member therebetween.

Referring now to these figures, A represents the usual hexagonal brush shaft which in my improved gin mechanism, particularly as shown and described in my application filed December 16, 1912 and Serial Number 736962, is mounted between the gin saws B and the lower mouth of a waste chute C adjacent to the mouth of which operates an internal stripping member C, this relation of parts being such that the brushes of the brush wheel D mounted on the shaft C take the dirt and impurities from the gin saws B and in turn deliver the same to the chute C through the action of the stripping member C, the impurities being sucked through the chute and discharged.

My present invention which relates par ticularly to the construction of the brush Specification of Letters Patent.

wheel D contemplates the provision of juxtaposed disks D and D each of which has a central hexagonal opening by means of whlch it is splined upon the shaft A, and each of which is also provided with an out standing annular flanged at its outer edge. The brush wheel also includes a rim D secured upon the outer flange d of one of the disks and lapping the other disk in such manner that the latter may be moved toward and away from the disk carrying the rim. Through these means the disks D and D may be readily adjusted away from one another and a washer or like member disposed upon the shaft A between the disks in order to selectively space the same apart, such a washer being of course of a desired thickness and one thereof being indicated at E in Fig. 5.

Each of the disks D and D is provided around its central hexagonal opening, with a clrcular series of slotted openings (1, each of which openings is elongated in a radial direction and disposed at a slight angle with respect to the axis of the disk, and has the material therefrom bent outwardly at right angles to the face of the disk in order to form a plurality of projecting lips (Z The brush blocks F are molded with embedded bristles F and formed with under cut lateral extensions f at the same side and adjacent opposite ends thereof whereby they may be firmly and securely positioned upon the lips. Thus the two pairs of brush heads with their bristles are formed upon opposite sides of each brush wheel whereby to operate upon the sides of the teeth of adjacent saws B between which a peripheral portion of the brush wheel projects, it being clearly apparent that, through the means previously described and by virtue of the particular formation of the brush wheel, the pairs of brushes may be adjusted away from one another and compensate for the wear of the brushes in action.

I claim l l. A brush wheel comprising a pair of disks each of which is provided with a central shaft opening and an outstanding annular flange upon its outer edge, a rim secured to surround the flange of one of the disks and loosely lapping the'fiange of the other disk whereby to permit of relative adjustment of the disks,'each of the disks being provided with a circular series of slotted openings around its central shaft opening,

the material from which openings is bent outwardly at one side to form a circular series of outstanding lips, and brush blocks having embedded bristles and provided with undercut lateral extensions at one side and adjacent opposite ends whereby to firmly embrace the said lips and maintain the brush blocks in position.

2. A brush wheel consisting of a pair of relatively movable juxtaposed disks, each disk being provided with an outwardly facing laterally projecting series of brushes, for the purpose described.

3. A brush wheel consisting of a pair of relatively movable disks, a rim secured to one disk and loosely lapping the other disk,

ries of outstanding laterally projecting lips,

and a series of brush blocks secured to the said lips and having outwardly facing laterally projecting lips, and a pair of brush blocks secured to the said lips and having outwardly facing laterally projecting bristles, for the purpose described.
